PAPER RECEIPTACLE.

Specification of Letters Patent. Patented Apr. 26, 1910,

Application filed September 19, 1908. Serial No. 453,894.

To all whom it concern:

Be it known that I, JOHN N. DAVIS, a citizen of the United States,residing at Dayton, in'the county of Montgomery and- State of Ohio, haveinvented certain new and useful Improvements in Paper Receptacles, ofwhich the following is a specification.

My invention relates to receptacles of paper or similar material andmore particularly to bottles of such material.

The object of the invention is to provide a bottle constructed'of paperor similar material which will be sanitary, simple in structure strongand durable to enable it to withstand the action of liquids, and whichmay be manufactured byunskilled labor at such low cost as will permit itto be discarded .when once used.

A further object is to provide a vessel of such character; which will besymmetrical, pleasing in appearance, and substantially conforming incontour to the usual shape of bottles heretofore used.

A further object is to provide an improved form of closure deviceforsuch receptacles, which will be -more effective in protecting thecontents of the receptacle from the entrance of foreign matter.

With the above primary and other incidental objects in View, theinvention consists of certain features of construction, devices,

parts and combinations thereof, or their equivalents, as hereinafterdescribed and set forth in. the claims.

In the drawings Figure 1 is a perspective view of the completereceptaclewith the closure device in place. Fig. 2 is a verticalsectional view of the complete receptacle. Fi s. 3 and 4 are plan viewsof the outside and inside wall members respectively. Fig. 5 is anenlarged detail sectional view of the upper portion of the receptacle.Fig. 6 is a similar view of the lower portion of the receptacle. Fig. 7is a view similar to Fig. 6 illustrating an alternative construction.The thickness of the paper as shown in Figs.'5, 6 and 7 is greatlyexaggerated, showing recesses between sundry layers of paper which inreality would not exist, or would be so small as to be unnoticeable inthe device when constructed from stock of usual thickness. 'Figs. 8 and9 are detail views of annular reinforcing members for the bottom of thereceptacle. Fig. 10 is a sectional perspective view of the closure cap.Fig. 11 is upper part of the bottle, showing the four fold seam of theinner wall.

Like parts are indicated by similar char- -acters of referencethroughout the several views.

The bottle as illustrated comprises a vessel cylindrical throughout aportion of its height, and inclined or conical throughout the remainingportion. The vertical walls or the cylindrical portion are of threethicknesses, while the upper portion which is in the formof a truncatedcone attached to said cylindrical portion is of double thickness, thedouble walls being scored and folded to cause the walls to contract tothe re-- duced mouth.

In constructing the receptacle there is employed a cup shaped member 1which may be formed by gluing and folding a paper blank in the wellknown manner, but is preferably formed from a paper blank by stamping,or by the use of suitable forming dies, whereby the paper cup will be aseamless body. There are provided inner side walls 3, which extend downwithin the cup 1 substantially to the bottom thereof, and outside walls2 which inclose the cup 1 and the inner walls. The outside walls 2 areformed from' a single blank of rectangular form shaped and "scored asshown in Fig 3, in which 4 are triangular, rentering gores formed byscoring the blank, which gores, when theblank is folded on the scorelines cause the upper part of the bottle to assume the conical form. At5 is provided a portion to form an overlapping glue joint, by

which the two sides of the blank are united.

The inner wall blank is shaped and scored similar to the outside wallblank, the gores 6 of the inner wall corresponding with those 4 of theoutside wall. Glue laps 7 are provided at each end of the blank, bywhich the blank is formed into a cylindrical body. The glue sections, 7are first joined, then the blank is folded on the score lines at eachside of the glue joint to form' a four fold seam, formed by theinterlocking of the reversed edges of the blank, which incloses the gluejoint and protects the contents of the tom of the cup, the upper part ofthe -receptacle is contracted b plaiting the walls, or folding inwardthe'gores 4 and 6 of the respective walls 2 and 3, which forms verti calplaits in the bottle wall as shown in Figs. 1 and 2. The inclination ofthe upper part of the bottle may be varied more or less by varying theproportions of the gores etand 6,

making them wider and shorter for a more abrupt top, and long and narrowfor a slight tapered bottle. When the upper part has been contracted bythe folding of the gores on the score lines, the tongues 8 projectingfrom the upper edge of the inner wall are bent outward over the edge ofthe outside wall and attached thereto by glue or otherwise. This willserve to unite the double wall, and form a smooth finished edge. Annularreinforcing members which may be in the form of a band 9, as in Figs. 6and"8, or one or more flat rings, as in Figs. 7 and 9 are insertedwithin the extended outer wall 2 below the bottom of the cup 1, overwhich reinforcement, the lower edge of the outer wall is turned inward,as in Figs. 6 and 7, forming an annular flange or rim aboutthe bottom ofthereceptacle on which the cup 1 will rest, and which will materiallystrengthen the bottom of the receptacle to enable it to withstand theweight of the con tents.

Fitted over the top of-the receptacle is a collar comprising an internalflange 10 adjacent to the mouth of the bottle, having a peripheralflange s stantially inverted U shaped, extending pward 'on' the interiorand another at 15. It is to be understood that the thickness of materialis greatly exaggerated in this View, and that such recesses do not infact exist in the device constructed from material of proper thickness,but such recesses are due to the exaggeration of the view. A closuredisk as is incommon use for closing milk bottles may be used with thereceptacle, such disk being pressed within the mouth of the receptacleuntil it rests on the flange 10 of the collar. However such disks havebeen found undesirable for the purpose of closing milk and otherbottles, because dirt and foreign matter collect on top of the diskwithin the orifice of the receptacle. To remove such disk closures it isusual to pry the disk up, the tilting of which in the removal operationresults in spilling the dirt from-the closure disk into the contents ofthe receptacle. To obviate this difficulty, there is provided a closuredevice formed from a single piece of material by stamping or otherwise,which rests on the flange 10 and overhangs the upper edge of thereceptacle walls.

The closure comprises a cup shaped member 16, the peripheral flange 17of which is recessed, or substantially inverted U-shaped, within therecess of which the edge of the receptacle -wall extends. The closuredevice is somewhat similar in shape and in application to thereceptacle, to the collar before described, except that the horizontalportion of the collar is provided with a central opening, whereas thatof the closure is continuous or solid. B the use of the closure asdescribed, any dirt or foreign matter which might be on the closure willbe removed therewith, and can not accidentally fall into the receptacle.The flange 'of the closure engaging closely both the inside and outsideof'the edge of the wall forms a slop proof joint, which not onlyprevents the entrance of foreign matter but also prevents the escape ofthe contents of the receptacle.

It is obvious that instead of the gores 4 and 6 in the walls of thereceptacle, such Walls might be corrugated without scoring the materialsuch corrugations being compressed at thetop, somewhat fan shaped toform the tapered portion of the receptacle.

From the above description it will be ap parent that there has been thusproduced a receptacle 1 of the character described, in which the gluejoints will be protected from contact with the contents thereof, andwhich possesses the sundry other features of advantage before enumeratedas desirable, but which obviously is susceptible of modification in itsform, proportion, detail construction, and arrangement of parts withoutdeparting from the principle involved or sacrificing any of itsadvantages.
